Question

What are two adjacent sides of a rectangle are 5x2-3y2 and x2+2xy.Find the perimeter?

Answer 1

Answer:

12x² + 4xy - 6y²

Step-by-step explanation:

Length of rectangle = 5x² - 3y²

Breadth of rectangle = x² + 2xy

Perimeter of rectangle = 2(L + B) = 2( 5x² - 3y² + x² + 2xy)

                                                       = 12x² + 4xy - 6y²
